Floyd saw specialists for much of last season after playing only in the team’s first game. The Vikings have said he is continuing to rehab.

His $6.757 million fifth-year option, which was previously guaranteed only for injury, became fully guaranteed March 9.

Floyd, a former first-round pick, dealt with knee injuries in 2014 and 2015, and he missed much of the Vikings’ 2016 offseason program because of ongoing issues after having a piece of cartilage removed from his left knee during the 2015 season.

After playing in the Vikings’ season opener at Tennessee, Floyd was ruled out for the home opener against Green Bay on Sept. 18, and he underwent surgery on his right knee on Sept. 22.

His injuries drew the ire of coach Mike Zimmer, who’d said he was “kind of used to” Floyd being hurt.

Floyd was shelved long beyond what the Vikings initially expected. They kept him on their active roster until Dec. 12, effectively playing with a 52-man team. When Zimmer was asked in November why the Vikings hadn’t yet put Floyd on injured reserve, the coach said, “We didn’t think it was going to be six years’ worth of hurt.”

When the Vikings placed Floyd on injured reserve, Zimmer said that the tackle hadn’t had a second operation after his initial surgery in September. However, USA Today reported on Thursday that Floyd had a subsequent operation after his initial surgery.
